Tree in Burma exceptionally brown (8)

I believe the answer is:

rambutan

'tree' is the definition.
(rambutan is a kind of tree)

'burma exceptionally brown' is the wordplay.
'exceptionally' indicates an anagram.
'brown' becomes 'tan' (tan is a kind of brown).
'burma' is an anagram of 'rambu'.
'rambu'+'tan'='RAMBUTAN'

'in' acts as a link.

(Another definition for rambutan that I've seen is " Bright red Malaysian fruit".)

I've seen this clue in The Telegraph.
